sudo apt-get install build-essential will fix it.
Thanks you so much!
I still don't know what caused everything to turn bad.
This happens when I attempt to send an email through the ACP.
The sendmail executable could not be found, please ensure it is installed and executable by the user running NodeBB.
If you know a solution for this, please reply asap!
@ExoticButters Log in in your server with the user you use to start Nodebb and try sendmail from the terminal. It should be available in user path with the right permissions on it.
It needs a mail server/address to send those mails from. By default NodeBB tries to use the SendMail application for this. As you don't have that installed (I assume) it gives that error. Personally I'm using MailGun (with this plugin) instead of SendMail for this, because SendMail is complicated to set up.
Are you on Windows? If so, sendmail isn't available, so you'll have to install a real emailer.
Yes. I am using Windows 10. Ermm... is there anyway to have a mail service without changing my operating system?
@ExoticButters use a third party emailer service with a nodebb plugin. All of them offer free plans.
